Thus this is the great battle of life – to master the passions. The power of this was demonstrated by Christ on the Cross. Even though He suffered the greatest injustice – being physically crucified and humiliated – Christ did not get angry at His tormentors, but rather forgave them – showing the great power of forgiveness and self-mastery over evil. Instead of this evil act leading to more anger and retribution, it led instead to the ultimate demonstration of forgiveness which was so powerful as to influence the entire culture of the Western world for the next two thousand years.
Thus, it is the Christian’s duty – before all others – to master his or her own passions. That is not too say one should become overly ascetic or stoic like Diogenes - Christianity is a religion of moderation, not prohibition, rather one should take what is given with gratitude to God yet not indulge one’s senses or desires, except the desire to love.
